Abstract (en)
[origin: WO2011000943A1] The invention relates to a hub of a propeller with variable-pitch blades for a turbine engine, in particular for a propfan engine. The hub of the propeller comprises a polygonal ring (234) with substantially radial cylindrical recesses (236) distributed about a central axis of the ring (234) for receiving said blades, a turbine rotor element (243) of the turbine engine, and a securing flange that is attached to the ring so as to connect said ring to said rotor element (243). The hub further comprises a plurality of back-up hooks (244) inserted with clearance in openings (241), the back-up hooks (244) being connected either to the ring (234) or to the rotor element (243), and the openings (241) being connected to the other one of the two.
